JOSM crash after keyboard language changed (MacOS)

[Mashin]

What steps will reproduce the problem?

1. I started JOSM from Terminal as java -Xmx10000M -jar josm-tested.jar
2. I had some data loaded, Search window open and needed to switch system keyboard language
3. JOSM crashed (happened a few times due to these same reasons)

Please provide any additional information below. Attach a screenshot if possible.

this is the output from Terminal

I wasn't able to reproduce with Java version: 11.0.12+7, Eclipse Foundation, OpenJDK 64-Bit Server VM on Mac OS X 11.5 (you are on 10.16).

First question: Can you update your Java version to 11.0.12 from 11.0.11? (Note: JOSM now recommends Azul/Bell Software Java distributions for Java 11+, as they have JavaFX included). Or you can use the MacOS package (it has a built-in version of Java, I think it is either Java 16 or Java 17).

Second question: Which keyboard language did you switch to? I used Greek, but this may make a difference.

That update to 11.0.12 fixed it.

Thanks for looking into this!

Java bugs are fun. It is nice when an update just "fixes" the issue.

Thanks for getting back to us.
